Wednesday Morning Update

Due to storms in the area, I'll be brief with the morning update.

A few scattered showers or storms will be possible this morning before weakening by midday.  But additional storms will be likely this afternoon and evening across part of northern OK and southern Kansas.  Some may be severe with large hail and damaging wind the primary threat.

Storms formed last night across western OK and moved eastward overnight.  These storms have weakened across Northern OK this morning, but a few strong to severe storms are still possible across the southern part of the state for the early morning hours.  A stationary boundary located across southern Kansas will get a shove southward during the next few hours and will end up positioned across the northern third of state late this afternoon and evening.  Another weak upper level wave will approach the area helping to spark off scattered storms that will form small clusters of storms.  A few of these could be severe with large hail and damaging wind gusts.

This active weather pattern should remain through at least Midday Friday before the focus will be shifting southward across the Red River Valley into Texas.  Remnant moisture from Hurricane Miriam currently off the Baja will move across the southwestern U.S. and into the southern plains.  As this occurs, a surface boundary will slide southward across Oklahoma Friday with a surface ridge of high pressure building down across the Midwest.  This will effectively keep most of the Miriam moisture confined to our south Saturday.    I'll keep a slight chance of showers and storms Saturday morning, but if all goes as planned, the higher likelihood will be south of I-40 into Texas.  Sunday appears super nice for northern OK and southern Kansas with sunshine and highs in the upper 70s after morning lows in the 50s.

The pattern should be nice and fall like early next week with morning lows in the 50s and 60s with highs in the lower 80s.

Precipitation for the year is currently 23.13 inches, which is -7.93 below the normal average to date of 31.06 inches of precipitation.

Sunrise this morning will occur at 7:15AM with sunset tonight at 7:14PM.

The normal high is 80 and the low is 58.  Daily records include a high of 96 from 1938, 1920, and 1905.  The low is 37 from 1912.
